What's the difference between torque sensing and cadence sensing bikes?Updated 9 months ago

Cadence and torque sensing are two primary types of pedal-assist systems used in e-bikes, each operating differently to provide assistance based on the rider's pedaling input:

1. Cadence Sensor:

   • 
     
   • Functionality: Cadence sensors detect the rotation of the pedals (pedaling cadence) and provide assistance based on this movement. 
   • 
     
   • Operation: When the rider starts pedaling, the sensor registers the pedal rotation speed and activates the motor to provide assistance according to predetermined power settings. Vvolt uses high quality 10° cadence sensor for near instantaneous engagement and disengagement.

   • Qualities:
     • Simple Operation: Cadence sensors are relatively simple in design and implementation. Vvolt cadence sensors are in the form of a replaceable square tape bottom bracket. 
     • Consistent Assistance: They offer consistent assistance regardless of the pressure applied to the pedals. This can help when you're feeling kinda tired! 
     • Smooth Riding: They provide a smooth and predictable riding experience, ideal for leisurely rides and quick trips in the city alike! 
     • 
       

2. Torque Sensor:

   • 
     
   • Functionality: Torque sensors measure the force applied to the pedals by the rider and adjust the motor assistance accordingly.
   • 
     
   • Operation: When the rider exerts more force on the pedals (pedaling harder), the sensor detects this increased effort and instructs the motor to provide more power. Conversely, reducing pedaling force decreases assistance. 
   • 
     
   • Qualities:
     • Responsive Assistance: Torque sensors offer a more responsive and intuitive riding experience, providing assistance proportionate to the rider's effort.
     • Efficient Power Delivery: They optimize energy consumption by providing power when needed based on the rider's pedaling intensity.
     • Natural Riding Feel: Riders often find torque sensors offer a more natural and engaging riding experience, especially on varying terrains or when climbing hills.

Cadence sensors offer simpler operation but may provide less dynamic and responsive assistance, while torque sensors deliver more intuitive and proportional assistance based on the rider's pedaling effort, providing a more natural riding experience albeit at a potentially higher cost and complexity. The choice between the two depends on individual preferences, riding style, and desired level of engagement with your ebike.
